DOOR-CHECK.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed April 8, 1905. Serial No, 254,522.

To aZZ whom it may concern:

Be it known that I, \VILLIAM H. MINOR, a citizen of the United States, residing at Frenchlick, in the county of Orange and State of Indiana, have invented new and useful Improvements in Door-Checks, of which the following is a specification.

This-invention relates to door-checks, and has for its objects to produce a comparatively simple inexpensive device of this character which will effectually check momentum of the door; at the completion of its closing movement, one which will maintain the door in closed position, wherein the door-engaging member will be normally maintained in and automatically returned to door-engaging position, and one in which strain upon the hinges is relieved when the door is in closed position and sagging of the door consequently obviated.

ith these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanyingdrawings, Figure 1 is a vertical longitudinal section centrally through a device embodying the invention and showing the same applied for use. Fig. 2 is a vertical transverse section taken on the line 2 2 of Fig. 1 and viewed in the direction of the arrow with the door omitted, and Fig. 3 is a perspective view. of the device.

Referring to the drawings, 1 designates a skeleton frame composed of metal and including side walls 2, upon the lower edges of which are formed laterally-projecting perforated ears 3, designed to receive screws 4:, by means of which the device is fixed in position beneath the lower edge of the door 5.

At one end of the frame 1 the upper edges of the side walls 2 terminate in upwardly-inclined cam positions 6, between which is disposed a vertical uprising stop member or abutment 7, preferably formed by a vertical extension of the adjacent end walls of the frame, while the opposite end wall 8 of the frame has its lower edge extended vertically downwardly below the plane of the walls 2 and sharpened, as seen in Fig. 1, to produce a depending engaging portion or flange 9, designed for entrance into the floor, thus to maintain the device in proper position while applying the screws L.

Pivoted at one end within the frame 1 upon a horizontal transversely-disposed pintle or axle 10 is a door-engaging member or check 11, provided upon its upper face and between its longitudinal center and free end with an upwardly -extending door-engaging portion or cam 12, having reversely-inclined faces 13 let, there being disposed beneath the member 11 and for maintaining the same in normal position a leaf-spring 15,- attached at one end to the frame or body 1 by means of a screw or other fastening member 16, it being noted in this connection that the inner face of the end wall 8 is beveled or inclined, as at 17, to constitute a stop or contact-face with which the free end of the member 11 contacts to limit its movement.

In practice when the door 5 is moved to closed position it will contact with the outer inclined face 13 of the member 11 and ride upward upon the latter, which will be depressed against the action of the spring 15. After passing the cam portion 12, by which its momentum is checked, the door will contact with the stop or abutment 7 and be brought to rest thereby in proper closed position, it being apparentthat when in the latter position the door will ride upward on the inclined faces 6, which latter serve to relieve strain upon the door-hinges and obviate sagging of the door. I/Vhen moved to open position, the door will contact with the inner inclined face 14 of the cam portion 12, thereby depressing the member 11 against the action of the spring 15 and permitting the door to ride freely over said member, which after passage of the door will be automatically returned to its normal position by means of the spring, the upward movement of the member being limited, owing to the contact of its free end with the inner inclined face 17 of the end wall 8.

From the foregoing it is apparent that I produce a comparatively simple inexpensive device admirably adapted for the attainment of the ends in view, it being understood that minor changes in the details herein set forth may be resorted to without departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is 1. In a door-check, a frame provided with a stop or abutment, a door-checking member pivoted at its inner end in the frame and having its outer free end provided with a cam portion, a spring acting upon the checking member to maintain the same in normal position, and means for limiting the upward movement of the free end of the member.

3 2. In a door-check, a frame provided at one IIO member pivotally mounted in the frame and provided with a cam portion, and a spring for maintaining the member in normal position, the cam portions on the member and frame being spaced relatively to receive the door between them.

In testimony whereof I afliX my signature in presence of two witnesses.
